REVERSIBLE STOP AND WASTE COCK.

Specification of Letters Patent;

Application filed November 9, 1909.

Patented Aug. 2, 1910. Serial No. 527,024.

To all whom it may concern:

Be it known that I, FRANK Wnrss, citizen of the United States, residingat Oleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Reversible Stop and Waste Cocks,of which the following is a specification.

My invention consists in a reversible stop and waste cock constructedand arranged substantially as hereinafter shown and de scribed and moreparticularly pointed out in the claims.

My object is embodied in a stop and waste cock having a plug providedwith a sealing cap which is primarily of advantage in keeping all dirtand grit from working into the plug seat. Such caps or covers have beenused heretofore, but I also employ a removable handle having a pair ofstop pro jections adapted to pass through openings in said cap to engagestop lugs upon the body of the cock. This arrangement provides forreversibility of the plug and also serves to effectively seal allopenings leading to the plug at its top. Again, the matter ofreversibility is simplified to a mere shift of the handle from eitherone of the two positions in which it is adapted to rest, and there areno complicated or hidden parts to be changed or to confuse a person insetting the parts.

to waste from the right. Fig. 3 is a cross section and plan view on line3-3, Fig. 1, and Fig. 4 is a plan view of the cock with the handleremoved. Fig. 5 is a perspective view of the handle, and Fig. 6 is asimilar view of the capportion of the plug.

In the assembled figures, main water passage 2 is shown open throughboth body 3 and plug 4, and waste opening 5 in the plug and waste outlet6 in the body are closed. As usual, waste opening 5 is located at theclosed side of body 3 so as to register with main passage 2 if the plugbe rotated a quarter turn in either direction, thus throwing main waterpassage 2 in the plug in open communication with waste outlet 6. Thisrotation of the plug is limited to a quarter turn by integral lugs 7 and8 projecting upwardly a short distance from the annular top portion 9 ofbody 3 in which tapered plug 4 is centrally seated. That is to say, saidlugs form stops for screw 10 which passes through cap 11 of plug 4 andfor long projection 12 extending downwardly from apron 13 of handle 14.In one instance and as shown in Figs. 1 and 3, screw 10 is adapted toengage stop lug 7 to limit the rotation of plug 4 to the left to permitwasting from the left side of the cock, and in this case handle 14 isset as shown to present its projection 12 in the path of stop lug 8 soas to limit the return movement of plug 4 to a quarter turn. In Fig. 3this last position is shown with projection l2 engaging stop lug 8. Nowassuming that it is desired to set the plug to rotate reversely from theforegoing, handle 14 is bodily removed from cap 11 and set in reverseposition with its projection 12 on the opposite side of the axis of plug4 and as shown in Fig. 2. This brings projection 12 opposite lug 7 butscrew 10 sustains the same position as in Fig. 3. Only now it must moveto the right and strike lug 8 to limit the plug to a quarter turn andwhich will place the plug in position to waste from the right hand sideof the cock. It is obvious that such reversal of the handle can only beeffected by providing the top face 15 of cap 11 with a pair of openings16, so that projection 12 may be entered through said cap in the tworadically different positions shown and described. And, it is alsoapparent that without apron 13, one of said openings 16 would remainopen, but as 1t is, said apron 13 covers both openlngs and prevents theentrance of dirt to the interior of cap 11. To further safeguard closingof both openings 16, a second but shorter projection 17 is used at thebottom of apron 13 to co-act with longer projection 12 in closing saidopenings. Projection 17 must necessarily be short otherwise it wouldcontact with lugs 7 or 8. Greater turning strength is also given to thehandle by reason of two projections thereon instead of one alone, andthe double engagement with plug 4 through openings 16 supplements themain one at the center obtained by square stem 18 socketed To preventconfusion or error in placing the valve plug 3 in its proper position inbody 3 and in placing handle 14 in either of its two positions on theplug, I provide a connecting web or upstanding rib 20 between lugs 7 and8 at the waste-outlet side of the cock. Because of said obstructing webor rib, screw 10 cannot be seated to play between lugs 7 and 8 at thisside of the cock, and projection 12 cannot be entered its full depth atthis side nor can handle 14 be seated improperly for the same reason.Screw 10 not only serves as a stop member but also serves to lock thehandle upon the cap. Its position is fixed however and is not shifted tomake any change in reversing the plug or the handle, except to unlockthe latter.

WVhat I claim is:

1. A reversible stop and waste cock comprising a body having a mainwater passage and a waste outlet, a valve plug having a waste opening, asealing cap for said plug having a pair of openings in its top, stops onsaid body and plug covered by said cap, and a removable handle havingmeans to close both said openings and being provided with a projectionadapted to enter either one of said openings to engage the respectivebody stops.

2. In a reversible stop and waste cock, a valve plug having a sealingcap at its upper end provided with a set of openings in its top face, incombination with a detachable operating handle for said plug having astop projection adapted to occupy either of said openings and having aseparate portion adapted to close the other opening.

3. In a reversible stop and waste cock, a valve plug having a sealingcap with a pair of through openings in its top, in combination with adetachable and reversible handle for said plug having an apron to coversaid cap and its openings and provided with a projection adapted to passthrough either of said openings into the inside of said cap, whereby thebody of the cock may be engaged by said projection and the cap be closedat both openings by said apron.

l. In a reversible stop and waste cock, a

valve plug having a sealing cap with a pair of through openings in itstop, in combination with a detachable and reversible handle [having apair of projections adapted to occupy said openings in either of tworeversed positions, one of said projections being longer than the otherto form a stop for said plug when the parts are assembled.

A reversible stop and waste cock comprising a body having a main waterpassage and a waste outlet, a valve plug having a waste opening andprovided with a sealing cap having a central recess in its top for ahandle and a pair of openings at the side of said recess adapted toreceive a projection on said handle, and stops and a connecting portionbetween said stops to limit and obstruct the said handle projection, incombination with a handle having an apron to cover said cap and providedwith a projection adapted to pass through either of said cap openings toengage said stops, and aseparate stop member for said plug within saidcap located intermediate its top openings.

6. A reversible stop and waste cock consisting in a hollow body having amain water passage and a waste outlet, a valve plug having a throughwater passage and a waste opening, stop lugs and a connecting webbetween them on said body, an integral cap on said plug covering saidlugs and having a pair of through openings in its top and a centralrecess for a handle, a screw FRANK WEISS.
